Be it known that I, WILLIAM HENRY 4Don- MAN, a subject of the Queen ofGreat Britain, residing at Staiord, England, ha'VeJnvented newand'useful Improvements in Nailing and Lasti'n g Machines for Shoes,(for vwhich I have obtained a patent in Great Britain, 'No.'23,363,dated December 6, 1895,) ot'which the following` is a specification.

' My invention is for improvements in machinesfor putting nails ofvarious sizes into shoes, from hobnails to lasting tingles or tacks; andit consists of the lfollowing fea tures-that is to say:

Theftacks are put into a hopper and pass from it delwn a chute. At'thetermination of the chute is placed a reciprocating lnail-carrierconsisting of au arm which makes a semirevolution about -a pivot and'each time takes a nail from the end of the chute and carries :it arounduntil it is just under the hammer. There arc suitable shutters actuatedat suit-' able times which respectively shut .up the end ofthe chutewhen the carrier leaves it and shut the nail into the carrier. nailarrives underneath the hammer, the carrier stops, and the hammer, whichis magnetized, descend'sclo'se to the head of the nail,

which is attracted to it, and immediately rises again, liftingthe`adhering nail'clearout of the carrier, which at once returns to fetchan- -other'naiL As soon as the carrier is outlof the Way the hammerdescends, with the nail', and drives it into the shoe, which is held ina suitable position below. r A

I employvarious gages for determining the position of the' shoe while inthe machi`ne+n an edge-gage, against which the edge of 'the boot rests.edge of the sole 'or sometimes the corner formed where the upperloverlaps the insole, or, again, it may be the feather of the boot, oreventhe edge ofthe top piec.. 'This edge-gage overlies the edge, so asto form a ledge against which the boot can be pressed upward vand has a:face more or less at right angles to' it', lagainst which the .boot maybe pressed sidewise, and is made of 'diderent shapes and isadjustablein. different directions to suit the different kinds of Work'tol be'done.- -Itis sometimes used- `fixed and Sometimes is allowed to' slideinan'd out underthe This edge may sometimes be the control of'la springand-is locked faistjustbe fore and during the time the upper is beingpulled'upli'ffthe boot is being lasted) and the "nail is beingput in. Agage is also used against whichthe side of the boot rests. This' gage ison aslide and under-the controlof a,

`spring and is .lo'cked at the necessarytimes. A gage is occasionallyused that takes into'the y channel onth'e insole anduassistsuin vguiding'j the work; also, a gage that takesgonto the surg y face'of the sole orinsole and assists in determining the angle at which the boot ispresented to the machine. Thesegages (are adjustable and may be used/fixedorwith a slight, '4 duly-timed lifting movement to facilitate themovement of the shoe.

The surface gage is sometimes required t`o have inaddition anup-and-down-movement governed-by a spring, and saidgage is locked 'atthe requisite times.

Thev g'ages are not allv necessarily employed at one time, but aremadeuse of as occasionl may require .to suit the various kindsoffworkto, be done. f

The boot iscarried upon a framef commonly l f known as a jack,? ofwhihthere aremany varieties in use. The jack is supported upon a postwhichfrests in afhookl-joint.npona treadle or lever, by `means` ofwhichfthe boot is held up against the gages abovementioned U with suclia degree Tof force asfmay bedesired and by means of whichit maybereadily disengaged when, the` operation "iscompleted The jack sometimeshas a slightnpfanddown movement, orat leastthe boot is. periodically Y.

released from pressure ,againstl the gages,l so that its movement'lnaybe' ij'acilitated.;v 5x1 g l My'invention also consists, Yin,conjunction with the above, of a pair of mechanical .pin-

cers actuated bythe machine, which is used i to lyhold of and drawtheupperfiover the last; The'- pincers are adapted togrip differentthicknesses of lmaterial and to exert .a degrec of drawing 'strain-uponthe upper, varif able at pleasure. The action of the ,pincerslocking-bar which is connected to the jack vor 2: .jack-post by ahook-jointand 'passes tslil'mlghv aj'cup and K balll mounted in, thecolumny ,on

them and bring'the bottom vtack truly vertical and'insnreitsbeing inits'proper position in the notch (111 `before the arm d moves away.

This divider e may be operated by a cam e'. j

` p and the shoe is held up under the hollow and lever e2 from the shafta2.

For the purpose of sealing the open end of the chute c1 while the arm dis a\vay,' I provide-another shutter-arm f,-also loose upon the pivot dand having an end like the arm d, but withoutlthe vertical notch du. Thearm f lies against thevarm d on the opposite side to the arm d, and whenthe arm d moves away the -arm ffollows it, moved by the pressure of thespring f' into the place just vacated by thearm (l and shuts the end ofthe chute c1, until pushed away again by the returning arm d.

So that the bootmay be properly presented relatively to the hammer b'and other parts, I provide an edge-gage g, which has a horizontal notchg', against which the edge or cor- 'nerwhere the upper turnsover on theinsole inay be pressed vby the operator and which furnishes a-guide forhim in feeding along the boot.A This gage g may be used fixed and madeadjustable vertically and horizontally or it may be mounted upon a slideg2, carried lin the frame a and held forward bya spring g3, beingretained in any position to which the operator' may have pushed it whilem'a- V'nipulating the boot by a ratchet-wheel g1 and pawl g5, connectedby a pinion -g6 and rackg7 -with the slide g2, the pawl being unlockedatsuitable times by the operation of the machine,y

the arrangementv somewhat resembling that described in the specificationof a'British patent grantedI to ine, No. 11,437, A. D. 1895. I mayprovidealso a gage h, which is similarlyT mounted and operated, having aspring h' which bears it forward against the upper, yielding wheny theoperator presses upon the boot, the gageV being locked by the machinepreviously to the driving of each tack, and, if

desired, before the gripping movement of the pincers, hereinafterdescribed, takes place, bythe operation of a camhz, which is mounted outhe sbatte2 and'acts on a roll h3 and lever.

h4, .mounted ona' pivot h5 in the frame a', the lever being jointed to arod h6, which carries an arm hl, engaging ay lever hs, mounted on ashaft h9 in the iframe a', the shaft h1 also carrying a pawl hm, whichengages vthe teeth of a ratchet-wheel 7111. The ratchet-wheelh11ismoun'ted'on a shaft k12, alsov carried in the f-ramelva and havingmounted npouit a pinion XL1S, gearing in a rack h11 upon'the slide h15,which is vf'ree to move inthe frame a' and carries the 'j gage -ri.`Th'e movement ofthe surface gage is precisely` similar,jbnt`is in avertical-instead otla horizontal direction and is not illustrated."` j lOneforrn otsurface gage v'whichis" used in going around the seat oftheheelis illustrated in Figs, 22jand`23. v It is mounted beneath theportion'a. of the frameon 'a'pivotpand stands when iri'use in thepositionfpf," .being held against the stop p2 by '011B SPF'Ug'Ps! Whenturned horizontally, so as to be out of use, into the position p4, itlies against the stop p5. The tacks are driven through the hole p7against the teeth ps. The handle p1 is for turning the gage into or outof position.

When it is desired to give to any of the gages a slight duly-timedlifting movementto facilitate the movement of the shoe, the arrangementis the same in principle as that described in the specification of aBritish patent granted to C. F. Gardner, No. 2,591, A. D. 1885, andtherein illustrated in Figs. 2, 3, and 15 for giving a movement to thehorn N.

To pullthe upper over onto the insole, l provide pincers actuated bythemachine and in one form, as shown in Figs. 15 and 1 7, constructed asfollows: A shaft t' is carried in the frame'a7 and'operates,through'gears 'i' i2 is 54, a shaft i5, which is also carried in theframe a7 and carries a cam 1', which operates at the proper time betweenthe arms i7 i8 of the pinces, so as to open'the jaws 9.10 about thepivot '511, which jaws are afterward closed upon the edge of the upperby the spring 12. The pivot @'11 is carried by an arm/13, which hangsfrom another pivot 14 in the frame a7. A second camv @'15 on the shafti5 acts upon a roll 16, mounted on the arm i1", so as to swing thepincers in at the proper times toward the machine against the tensionofa spring i", which is carried by an arm @'18 of the frame 0.7,andvwhen released by the cam '1115 the arm @'11 is pulled outward by thespring i, so as to draw the upper, which has been previously gripped bythe jaws if' @'10, over the edge of the last .'zz'and insole Thisarrangement may be reversed and the cams made to close and pull on thepincers', while the springs open the jaws and return the pincers afterthe pull. Another construction ofpincers is that shown in Fig. 7, in'which I provide 'avertic'al bar j,

IIO

which carries at its .lower end the lower jaw j of the pincers and isretained vin place by an upper eyepiece 3'2, mounted o n its pivotj3 inthe-frame a', and by a' lower eyepiece 7"1, carried by its stein ji in aslot j6, 'also in the frame a. I A set-screw jl allows of the bar jbeing set up and down in the eyepieces jg and f1. A face-cam js on theshaft n.2 acts' upon a roll j, retained upon the bar j by collars 3'10j, so as to move the jaw j inward, and a spring j12- serves to move itoutward. v The upper jaw 3'1"" of the pincers is mounted on a pivotL7'1" in the lower jaw j and is operated by an edge-cam j15, which actson a rollj16 and lever j", whichis mountedonv a pivot j13iu j@ to a rodjfzo'and link jm, connected to thel pincer-lever j. The jawj'is closedupon adjusting-screw j, against which the bar j takes. Aspringf'topensthe jawj3 when released `by t'he cam j?.

In the form of `pincers illustrated lin Figs. l and 2 the cam 7'25 opens'the pincers-jaws, while the springj26 closes them when released. Thepresser-foot'illustrated in Fig. 8 and which may be -used i'n'lien ofpincers is for the same purpose as and acts in a similar manner to thatdescribed' in the specication of-a British A. D. 1895.

If the machine is intended to luse either ot' two lengths of tack atwill, two cylindersand chutes are employed,the arrangement being verysimilar to that described in the specification of aformer British patentgranted to me, No. 18,374, A, D. -1894.. The operator by' means yof ahandle 7c(see Figs. 15 and 16).and quadrantk', 4mounted on av pivot k2.in the frame a', slides' the rack k3, *frame 47a4, and

cylinders 105106 to theright'or left, according` `asile-wishes tobringeither' the one or the other fof the chutes k7 ksinto position tosupply tacks to the tack-carrier. v j y T o prevent the tacks runningout vof `the ends of the chutes la7 las lwhen removed 4from, oppositethe carrier, I 'provide ahorizon-tal Hat-sided bar l, Figs. 15,16, 18,yand 19, against which the 'ends' of the chutes slide vand by.

which the open ends of the chutes are sealed.

This bar is-a xture and has anarrow cross slot ZV formed -in it for thepassage' of the ,tacks just where the carrier operates, and a hollow Z2isformed in one side of the bar Z,

having lthe same radiusof curvature as the' end of the carrier-arm d, sothat 'the latter can enterand leave properly; When a chute, as k7, isplaced exactly coinciding with the slot`l,.thevtacks canpass'to thecarrier; but 1n all other positions the chutesk7 ks are sealed by theflat side of the bar l. The boot and lastV may be carried upon a Jack,whlch maybe of any suitable construcition, or maybe held to themachine-by hand.

. In order-that the pulling action of the pincers may nothaveto beresisted by the operator, 'I provide an arrangement which locks thejack'immovably in any position in wh ich the operator chooses to -placeit priorto the action of the pincers and hammer taking place. VThe jackm, Figs. 1 and 2, is mounted on .a post m', carried by a hook-joint m2ona treadle-lever 'm3,' which is mounted on a pivot m in the columna,and the whole is balanced byla weight m5. Theupper portion Im6 of the'jack rm. is free to be turned around upon the lower portion m", and awheel ma is providcdon the portion m6 and turns with it.

lhe wheelmgears into av pinion m, which 1s mounted on a shaft m10,carriedin the portion mi of the jack andconnected by a secondhook-.joint 'r/ to a shaftml, (see also Figs. 3, 4, and 9,) which passesthrough a split ball 'm1s in the column a. The split ball m13 is carriedin a pair of cups, the one, m, being. fixed to the column a and theother, m15., be-A patent granted tome, No. 7,494,

ing'provided with a stem m", which passes out .through the column .sideand is acted upon bya locking-lever m1?, which is piyoted on a pin m1?to the column a and drawn'inward by springs m19, so as togrip fast thecups on Ym15 upon the split ball 'm13 and the ball 'upon the shaft m12,so that the latter can 'neither revolve, swing, nor slide andthe jack.bef

comes immovably fixed. The jack is un; locked by the action of the camh2 and rodjt, described in'connection with the gage 7L. The' :rod hi isjointed to a lever m2, mounted-.on a

vvpivot m21 -in the column a,its end m22, when thru'st dow-n by therod'h, taking on the l`ock= ing-1ever m17 and thrusting the sameoutwardl against the resistance of lthe springs mi, re" leasing the cupsmum and ball 711,13, so as to leave the shaft m'free either torevolvewhen 'the jack isrevolved, swing whenl-the jack is swung sidewise, orslide when the jack 'is moved to or from the column.

If' the machine is intended to be used for drivingvnails into soles ortop' pieces either 'forati-aching themto the boot or for'increasq. ingthe wearing properties thereof, .the aforo# .said or other suitableVjack may sometimes be 'used or a horn or stump may be employedinanyfusual manner.V During .the feeding movement of the work, which maybe performed `by 'an awl in a manner/somewhat similar to that-describedin the specilcation of a British pateut granted to nie, No. 17 ,407,J

A. D. 1894, the'jack or horn mayibeadrawn down by a camandJratchetmovement like that described in the specification of the said Britishpatent` granted to 0. F; Gardner, No.`

.2,591, A. D. 1885, and already referred to. The pincers are dispensedwith, as may also be-tliejack-locking arrangement. 4The gages which bearupon the edgeof either thesole loo or the toppi'ece to regggulate"theldistance ih ns gives a'to-and-fro'feeding movement tothe slide n, whichis mount-odin the imain frame a and carries the aforesaid slide lna. The

magnetized hammer b is operated, as before v described, by the cam `b,and the cylinder c', chute c, and nail-carrier all operate as a1- readyexplained. The magnetized hammer b' carries down the adhering nailvthrough a split nose-piece o, which centers the nail and .opens toallow of the passage of the nailhead,

the nose-piece o being carried upon a lever o', which is mounted on apivot o2 in the framea.

. and is operated so as to move to and frofunder thehammer and away fromthe advancingzawl n4 by the cam 03 upon the shaft a2.

The 'specific' construction of the jack or work-support is not hereinclaimed, but will form 'the subject-matter of another lapplication. 4
